Question

Find the density of a substance that has a mass of 75 g and a volume of 35 mL. Don't forget your units!

Answer 1

Answer:

The density of a substance that has a mass of 75 g and a volume of 35 mL is 2.14 $\frac{g}{mL}$

Explanation:

Density is a characteristic property of a substance that relates to the amount of mass it has per unit volume. In other words, density is the property that matter, whether solid, liquid or gas, has to compress into a given space (it measures the amount of mass in a given volume of a substance). It is calculated as the quotient between the mass of a body and the volume it occupies:

$density=\frac{mass}{volume}$

In this case, you know:

• mass= 75 g
• volume= 35 mL

Replacing:

$density=\frac{75 g}{35 mL}$

Solving:

$density=2.14\frac{g}{mL}$

The density of a substance that has a mass of 75 g and a volume of 35 mL is 2.14 $\frac{g}{mL}$

Answer 2

The density should be2.14 g/ml.

Given that,

• A mass of 75 g and a volume of 35 mL.

Based on the above information, the calculation is as follows:

$Density = mass \div volume\\\\ = 75 \div 35$

= 2.14 g/mL
